I had no idea after using it for four years so I just weighed it. 11 Kg (24.2 pounds). Part of that weight is the extra Sinar base plate that allows two uprights to hold the rail, imperative from my point of view to prevent what would be an inevitable twisting action without it. The weight is camera only and not things like film holders, etc.

Dave,

Thanks for posting the info on your camera. As I plan to hike, and maybe even do a few overnight backpacking trips with my 7x17, weight and bulk are more of an issue for me. It's not really an apples:apples comparison, but I expect my completed 7x17 camera to weigh about 12 lbs. give or take a half pound.
